- policy neutrality.
- It can't be censored.
- it can't be shut down
- and the rules cannot change from underneath you.

except it can be shutdown the minute it actually gets used by its inability
to scale.

what's the point of having all this if nobody can use it?
what's the point of going through all that energy and CO2 for a mere 24,000
transactions an hour?

It's clear that it's just a matter of time before it collapses.

Here's a simple proposal (concept) that doesn't pretend to set a fixed
block size limit as you can't ever know the demands the future will bring
https://gist.github.com/gubatron/143e431ee01158f27db4

We don't need to go as far as countries with hyper inflation trying to use
the technology to make it collapse, anybody here who has distributed
commercial/free end user software knows that any small company out there
installs more copies in a couple weeks than all the bitcoin users we have
at the moment, all we need is a single company/project with a decent amount
of users who are now enabled to transact directly on the blockchain to
screw it all up (perhaps OpenBazaar this winter could make this whole thing
come down, hopefully they'll take this debate and the current limitations
before their release, and boy are they coding nonstop on it now that they
got funded), the last of your fears should be a malicious government trying
to shut you down, for that to happen you must make an impact first, for now
this is a silly game in the grand scheme of things.

And you did sound pretty bad, all of his points were very valid and they
share the concern of many people, many investors, entrepreneurs putting
shitload of money, time and their lives on a much larger vision than that
of a network that does a mere 3,500 tx/hour, but some people seem to be
able to live in impossible or useless ideals.

It's simply irresponsible to not want to give the network a chance to grow
a bit more. Miners centralizing is inevitable given the POW based
consensus, hobbists-mining is only there for countries with very cheap
energy.

If things remain this way, this whole thing will be a massive failure and
it will probably take another decade before we can open our mouths about
cryptocurrencies, decentralization and what not, and this stubornness will
be the one policy that censored everyone, that shutdown everyone, that made
the immutable rules not matter.

Perhaps it will be Stellar what ends up delivering at this stubborn pace.
